Her cutie mark represents her agility (bc frogs are pretty nimble I guess? And… uh… jumping?? Ok just go with me on this one), which is good- considering she spends a lot of time getting cats out of trees and other similar tasks.
All in all, she’s a very helpful and sociable pony, and quite popular around Ponyville- despite not really making any purposeful effort to be popular.
She lends a hoof not only in the mundane issues across Ponyville, but also as an editor for Daring Do’s books. Frogger is quite an avid reader, and- though she’d never admit it- prefers romance novels to all others. Finally, she’s a total romantic, though it’s barely noticeable.
Fun fact: the huge wings aren’t due to my weird style; Frogger actually does have large wings.
